Sapphire 7990 still a good card?

Hi!
I have seen this on ebay:
http://www.ebay.com/itm/AMD-radeon-HD7990-X2-Sapphire-deux-cartes-crossfire-Perfect-for-mining-/322520804105?hash=item4b17bceb09:g:Xy0AAOSw1WJZHYnc

It's still a good choice for mining Etherum?

Many thanks!

According to NIST and ECRYPT II, the cryptographic algorithms used in Bitcoin are expected to be strong until at least 2030. (After that, it will not be too difficult to transition to different algorithms.)

I think it would be a better fit for mining Zec, it gets hot as far as I know, also if that price is for just 1 7990 then that is way over priced. You're better off getting rx 470/570s at that price.

Vendor sells two at that price!

LOL
What sort of PSU you need for pushing 6 of them? You might encounter all sort of issues with it.
I'd rather split the rig into multiple pieces.

You should mine zcash with that only if you have cheap electricity , this card is a power drawer very low efficiency , but if you don't care about electricity free or cheap then it should make a fast roi with zec.
